Deformation Mode can only be accessed while an image from the Axial Current Anatomy strip is selected.
While in Deformation Mode, the Balloon Boundaries are also editable, enabling you to adjust it according
to the most up-to-date location of the balloon.
Planning a Macro-spot after updating the treatment plan in Deformation Mode enables
the system to plan an optimal spots arrangement that considers the updated location of
all contours. This flow is preferable to planning a spot, and only then entering
Deformation Mode.

1. Click this button to enter Deformation Mode.
2. The Prostate Capsule contour will appear dashed and with 4 handles. Another handle will appear
at the center of the Urethra LEDR (in case it was drawn, see Figure 6-8).
3. Click a handle and hold while dragging the mouse to deform the contour.
4. To update the Balloon Boundary arc, click and drag the arc handle to change its radius, or click and
drag the arc itself to displace it.
5. Click this button to exit Deformation Mode and Apply Deformation. All images in the
Axial Current Anatomy strip will be updated according to the applied deformation.
6. Repeat the process on other slices, as required. The deformation will be interpolated between all
edited slices.
7. Click this button to add a spot on the desired Axial Current Anatomy slice.
In case a very large or irregular deformation occurred, if the Prostate Capsule contour
cannot be corrected accurately in Deformation Mode, return to Planning stage and
perform a Re-Draw procedure (see Section 6.9).
